The purpose of this document is to describe some hardware specification which is useful to develop a product with HUAWEI LGA module supporting PCM (Pulse- Coded Modulation). This document is intended for HUAWEI customers who are integrators and about to implement their applications by using our module.
The HUAWEI LGA module supports the PCM, which can be used for the module to transmit and receive digital audio data. Linear and μ-law codecs are supported. The HUAWEI LGA module uses the PCM interface as part of the audio front end; it easily allows for an external codec to be used instead of the internal codec. As an example, through the PCM you could connect a HUAWEI LGA module to a Bluetooth device.
The HUAWEI LGA module has one PCM port. Please refer to the Hardware Guide of the module that you are in use to know the PIN number of the PCM ports.

Question
How-to guide: How can we control, configure and establish a simple data connection for a cellular module in Linux systems using the open source ModemManager tool for modem control and connection management.
Solution
ModemManager is a open source tool for Linux that can be used to communicate with cellular devices for configuration, status check, connection triggering etc. It is capable of communicate over several types of device control channels such as QMI/RMNET, MBIM, MODEM / AT command etc.
It is hosted by the Freedesktop.org community and driven by Aleksander Morgado and other contributors, please visit https://www.freedesktop.org/wiki/Software/ModemManager/ for latest information, source code, API reference manuals, debugging tips, contribution, mailing list etc.
Keep in mind that ModemManager is not directly developed or driven by cellular device vendors and the compatibility cannot be guaranteed for the specific device you aim to use. Some vendors contribute with code to make their devices fully compatible, while others don't. However many cellular devices can be set to expose standardized types of USB network interface and control channel such as MBIM interface by USB-IF or the Qualcomm proprietary interface QMI that ModemManager will try to identify, and often manage to work successfully with.
Before continuing with ModemManager, a good thing to ensure is that you have common Linux driver modules available in your kernel build.
You can compare your own systems kernel config with the ones listed in the following FAQ:
Common Linux kernel modules and configs necessary for communicating with cellular modules over USB interface
Selections of these are commonly used by cellular devices and need to be available in order to have device drivers correctly loaded when devices are detected.
Start by installing ModemManager and its dependencies to your Linux system.
You can build it from source code release tarball found at freedesktop.org (install instructions included in the archive)
If you have a package manager in your Linux distribution, it can usually be installed through them also.
E.g. on Ubuntu using apt to install it and related dependencies:
apt install modemmanager libmbim-utils libqmi-utils
Keep in mind that Linux distributions sometimes rely on fairly old releases in their repositories and the development of ModemManager, libqmi and libmbim are on-going continuously. So is also the development of the cellular devices when the cellular technologies evolve. It is therefore recommended that you have a fairly recent version of ModemManager, libqmi and libmbim running in your system as well as when it comes to kernel version since the driver modules sometimes acquire patch fixes to be compatible with new chipset features etc.
Check Freedesktop.org pages for details on the latest ModemManager, NetworkManager, Libqmi and Libmbim releases.
Once you've installed ModemManager and rebooted your system, the service daemon should be running already in background.
Mmcli is the related command line interface tool which can be used to interact with ModemManager daemon through command line commands.
Check the version by command:
mmcli -V

From here we can see the IP details we've been assigned by the cellular network.
ModemManager does not assign IPv4 address details to the cellular modules network interface in Linux by itself.
When ModemManager is used in conjunction with NetworkManager and the cellular connection is managed by it, then the IPv4 address details will be collected by NetworkManager through ModemManager and automatically assigned to network interface when connection is established.
If the system does not implement NetworkManager, then the IP and routing configuration needs to be handled by user software/scripting.
Example:
Enable network interface in Linux:
ip link set wwan0 up
Set the IPv4 address acquired from bearer information above, the CIDR subnet mask can always be set to 32:
ip addr add 2.68.206.100/32 dev wwan0
Disable ARP:
ip link set dev wwan0 arp off
Set MTU value acquired from network:
ip link set dev wwan0 mtu 1500
Add a default or other type of route to the cellular network device (e.g. with a metric to set which route to prefer)
ip route add default dev wwan0 metric 200
Add the DNS servers reported by cellular network or use other public/desired ones.
DNS server addresses are handled in different ways depending on the Linux distribution and network manager used. Therefore please refer to related dist documentation for best practice to add / maintain DNS server addresses in your specific system.
sh -c "echo 'nameserver 80.251.201.177' >> /etc/resolv.conf"
sh -c "echo 'nameserver 80.251.201.178' >> /etc/resolv.conf"
We should now have a network interface passing data successfully, we can try it out by doing ping requests:

Question
How to use NetworkManager and ModemManager in Linux to automatically establish and maintain a cellular data connection?
Solution
Using NetworkManager and ModemManager in Linux to automatically establish and maintain the cellular data connection
In this FAQ we will show how to set up NetworkManager to automatically configure, establish and maintain the cellular data connection in your system.
NetworkManager and ModemManager are open source tool for Linux to manage several types of networks and interfaces such as ethernet, wifi, etc. It can also manage cellular WWAN interfaces through the ModemManager tool.
It is hosted by the Freedesktop.org community and driven by Aleksander Morgado and other contributors. please visit https://wiki.gnome.org/Projects/NetworkManager and https://www.freedesktop.org/wiki/Software/ModemManager/ for latest information, source code, API reference manuals, debugging tips, contribution, mailing list etc.
ModemManager is capable of communicating over several types of device control channels such as QMI/RMNET, MBIM, MODEM / AT command etc. But support for vendor proprietary or out-of-kernel drivers are limited. Such drivers are gobinet, simcom_wwan and other drivers provided by the vendors directly.
Many Linux distributions have NetworkManager and ModemManager pre-installed or they can typically easily be installed through the systems package manager.
In Ubuntu for example apt can install it for you by command:
apt install network-manager
Check with commands below that you have both tools installed in system and their versions.
NetworkManager -V
ModemManager -V
ModemManager (and NetworkManager) are continuously developed for better compatibility with the cellular devices, therefore it is recommend to use a recent version of the tools and in case of problem situations, evaluate the latest versions from source and check the mailing list archives for possible discussions on the problem experienced.
Keep in mind that NetworkManager and ModemManager projects are not directly developed or driven by the cellular device vendors and the compatibility with the device you aim to use can be limited. Some vendors contribute with code to make their devices fully compatible, while others don't. Many cellular devices can be set to expose standardized types of USB network interface and control channel such as MBIM interface by USB-IF or the Qualcomm proprietary interface QMI that ModemManager will try to identify, and often manage to work successfully with but there are exceptions also.
Both NetworkManager and ModemManager have command line interfaces (nmcli and mmcli respectively) where you can interact with the management tools.
Relate to the following FAQ if you want more details for using ModemManager only to configure and control the cellular device but manually establish, maintain the connection and network interface IP address details.
How-to guide: control and set up a data connection in Linux using ModemManager as connection manager?
Have ModemManager list all the cellular device it has detected. Here we use the Alcatel IK41 series with MBIM interface in this example:
mmcli --list-modems
/org/freedesktop/ModemManager1/Modem/0 [Alcatel] Mobilebroadband
General details and status of them modem can be listed with "--modem" option.

Check that the cellular device is managed by NetworkManager by not having state "unmanaged" listed for it.
nmcli device status
DEVICE TYPE STATE CONNECTION
cdc-wdm0 gsm disconnected --
enp3s0 ethernet unmanaged --
lo loopback unmanaged --
Now you should create a connection profile in NetworkManager for your specific network carrier and SIM card with the "nmcli connection add" command:
For example:
nmcli connection add type gsm ifname '*' con-name '3-sweden' apn 'data.tre.se' connection.autoconnect yes gsm.pin 0000
- type is gsm for all typical cellular connections unless it is of cdma type.
- ifname is the control interface name, in this case cdc-wdm0, wildcard can be used also to have it autoselect.
- con-name is the profile name you want to give it.
- apn is provided by your network carrier and tells the modem what attach point it should use for the data connection.
- connection.autoconnect set to yes will make NetworkManager always try to auto connect and maintain this profile connection.
- gsm.pin lets you provide a pin code for the SIM card, that NetworkManager will try to use if PIN check is enabled for SIM card.
There are several additional commands and attributes available such as username and password settings for the APNs etc. Refer to the NetworkManager help and manual pages for full details on the commands.
If successful you should receive a reply similar to this one:
Connection '3-sweden' (cad6fcbf-2cb1-4796-b7e6-67b9f9635aef) successfully added.
You can check the status now by command:
nmcli device status
DEVICE TYPE STATE CONNECTION
cdc-wdm0 gsm connected 3-sweden
enp3s0 ethernet unmanaged --
lo loopback unmanaged --
Where connected should be listed as state if the connection establishment was successful.
If the connection is not successful or you want more details about the device and connection you can check commands:
You can list the current status with command:
nmcli radio
WIFI-HW WIFI WWAN-HW WWAN
enabled enabled enabled enabled
nmcli device show cdc-wdm

Ifconfig should now show the related IP address details already set to the network interface by NetworkManager:
ifconfig

The connection is successful and automatic reconnect is working when testing to unplug and plug in the device again.
For additional configurations, commands and available attributes, please relate to the manual pages for NetworkManager and ModemManager.
Troubleshooting logs:
NetworkManager and ModemManager write log messages to the Linux syslog file /var/log/syslog.
In case of problems with establishing a cellular data connection, please copy the logfile after the problem have appeared and include it in a Techship technical support ticket.
In some situations more detailed debug logs are needed, these can be acquired by changing the log levels for NetworkManager and ModemManager and run them manually.
To capture debug logs, please first disable and stop the normal services:
systemctl stop NetworkManager ModemManager
systemctl disable NetworkManager ModemManager
Run them manually in background with debug level set:
/usr/sbin/ModemManager --log-level=DEBUG &> /dev/null &
/usr/sbin/NetworkManager --log-level=DEBUG &
Reproduce the cellular data connection problem.
Once completed, kill the processes:
killall -TERM NetworkManager ModemManager
Copy the relate messages in syslog to a mm-nm-sys-debug.log logfile:
grep -E 'ModemManager|NetworkManager|systemd|dbus-daemon|dhclient' /var/log/syslog > mm-nm-sys-debug.log
Activate and start the services again:
systemctl enable NetworkManager ModemManager
systemctl start NetworkManager ModemManager
Include the mm-nm-sys-debug.log in a technical support ticket at Techship.com where you describe the issue in details and include other relevant information also such as kernel version, ModemManager and NetworkManager versions, dmesg log etc.

Question
What Linux kernel modules and configs are commonly used for communicating with cellular modules over their USB interface?
Solution
Most cellular modules can be supported in Linux by using som of the in-kernel drivers. The physical data interface to the host Linux system is usually done over USB which enumerates a set of different endpoints/interfaces. A set of serial interfaces for Modem/PPP, AT commands, NMEA location data and chipset debug information are almost always available in all configurations.
In addition some type of network endpoint/interface are also available and exposed. This can vary between manufacturers and chipset vendors and can also commonly be configurable by using USB configuration mode switching or through vendor specific AT commands.
Recommended kernel configurations to enable are listed bellow. Many cellular modules base their Linux support on these modules and drivers. Once included in the kernel build, the USB interfaces will be detected and bound correctly out-of-the-box or after applying source code patches to the driver modules.
Configs for USB serial drivers:
CONFIG_USB_SERIAL
CONFIG_USB_SERIAL_GENERIC
CONFIG_USB_SERIAL_WWAN
CONFIG_USB_SERIAL_OPTION
CONFIG_USB_SERIAL_QUALCOMM
CONFIG_USB_ACM
Configs for Modem/PPP support:
CONFIG_PPP
CONFIG_PPP_BSDCOMP
CONFIG_PPP_DEFLATE
CONFIG_PPP_FILTER
CONFIG_PPP_MPPE
CONFIG_PPP_MULTILINK
CONFIG_PPPOE
CONFIG_PPP_ASYNC
CONFIG_PPP_SYNC_TTY
Configs for USB network drivers:
CONFIG_USB_USBNET
CONFIG_USB_NET_QMI_WWAN
CONFIG_USB_NET_CDCETHER
CONFIG_USB_NET_RNDIS_HOST
CONFIG_USB_NET_CDC_NCM
CONFIG_USB_NET_HUAWEI_CDC_NCM
CONFIG_USB_NET_CDC_MBIM
Please relate to the Techship product specific web pages for vendor specific Linux integration guides.
Below is a selection of kernel commits relating to cellular module support in Linux kernels:

Question
How to activate the data connection for Huawei cellular modules over the USB network interface in Linux?
Solution
The first step is to assure that the Huawei cellular module is properly loaded in the Linux system. Huawei modules are most often automatically detected in recent Linux kernels, this can be verified in different ways by commands bellow:
The lsusb command shows what physical USB devices are detected in the Linux operating system:
lsusb
root@support-up2:~# lsusb
Bus 001 Device 005: ID 12d1:1f1a Huawei Technologies Co., Ltd.
The lsusb -t command shows the USB endpoints exposed by the detected USB devices and the related drivers loaded for them:
lsusb -t
...
|__ Port 4: Dev 5, If 0, Class=Communications, Driver=cdc_ether, 480M
|__ Port 4: Dev 5, If 1, Class=CDC Data, Driver=cdc_ether, 480M
|__ Port 4: Dev 5, If 2, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 5, If 3, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 5, If 4, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 5, If 5, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 5, If 6, Class=Vendor Specific Class, Driver=option, 480M
The dmesg lists all the driver loading logs since system boot up:

Enable the USB network interface in Linux host:
ip link set dev usb0 up
The command ifconfig list all network interfaces loaded in the Linux system, the cellular module interface can be named differently depending on the distribution used but generally named usb0, wwan0 etc. initially.
ifconfig usb0
usb0: flags=4163 mtu 1500

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 11 bytes 946 (946.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
the command ls can list the USB serial interfaces detected:
ls /dev/ttyUSB*
/dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2 /dev/ttyUSB3 /dev/ttyUSB4
Once this far we can now start communicate with the cellular module over AT commands. There are different applications available in Linux that enables manual communication with serial interfaces:
minicom -D /dev/ttyUSB2
socat - /dev/ttyUSB2,crnl
etc.
Try writing to the modem/AT serial interface initially the command "AT" it should return you OK:
AT
OK
Enable input command echo:

Question
I want to use the ME909u-521 with LTE radio access technology only.
I use the command AT^SYSCFGEX="03",40000000,2,4,40000000,"","" or similar, but the module won't lock to LTE only.
Why?
Solution
For modules with firmware 12.631.07.00.00 to 12.631.07.01.00
Since voice was included as a feature in this firmware, Huawei have removed the feature to lock to LTE only. The reason is that the majority of the current LTE networks doesn't support VoLTE (voice over LTE). The way the ME909u-521 solves this is by using a technology called Circuit Switched Fallback. This requires the use of the WCDMA or GSM network. Therefore the module won't allow blocking theses technologies.
For modules with firmware 12.636.11.01.00 and forward
The problem with voice still exists, so the module will need to do a Circuit Switched Fallback to handle this. With this firmware, Huawei introduced the command AT^CEUS, which can set the module in either data centric mode (1) or voice centric mode (0). If the module is in data centric mode, there will be no need to use the voice feature. Then the module can be locked to LTE. If you want to use the voice feature of the ME909u-521, you cannot lock to LTE at the moment.
Question
I want to use the diagnostic port on the ME909u-521. Can I do so?
Solution
The diagnostic port was open on the ME909u-521 until the firmware 12.636.11.01.00. If you want to use the diagnostic port you'll need to contact us so we can give you the shell codes to unlock the module. The shell codes are generated by the IMEI number on the module.
The command to open the diagnostic port is the command AT^SHLOCK. Send the AT Command AT^SHLOCK=1, to open the diagnostic port. The port will close when the module is power cycled or restarted.
